Abstract

The syntheses and characterizations of cyclotitanosiloxane (CTS) and cyclozirconosiloxane (CZS) were investigated. CTS and CZS were synthesized by the reaction of di-<i>t</i>-butoxysilanediol with bis(acetylacetonato)diisopropoxidotitanium(IV) or bis(acetylacetonato)diisopropoxidozirconium(IV) in benzene. The formation of CTS and CZS was confirmed by the NMR and IR spectra and elemental analysis. The X-ray structural analysis for single crystals revealed that CTS and CZS consist of an eight-membered ring of two titano- or zirconosiloxane linkages bearing two <i>t</i>-butoxy groups on a silicon atom and two acetylacetonato groups on a titanium or zirconium atom.
